The incident involved a Fox Lane Middle School student.

The Bedford school district is warning parents about a "suspicious and scary" incident involving a middle school student last week.

Superintendent of Schools Christopher Manno said in a Facebook post on Saturday that he has asked police for more patrols near school bus stops early this week after what was reported as an attempted luring of a Fox Lane Middle School student on Friday afternoon.

In a Nixle alert on Friday night, Westchester County police said the incident was not credible, but on Sunday they changed their assessment.

"An event did, in fact, take place and the details received justified an immediate and significant police investigation," police said in a Nixle alert on Sunday.

The incident involved a man who was in a parked car on a Mount Kisco street, Westchester County police spokesman Kieran O'Leary said today. The girl reported the man making a suspicious gesture to her, but the man told police that he was merely motioning to allow her to cross the street, O'Leary said.

The man was not arrested, and police said there was no threat to the community. O'Leary said the girl did the right thing by being cautious and telling an adult about her suspicions.

"Based on the perceived circumstances of this event, those who reported the incident did exactly what law enforcement encourages of any victim of or witness to a suspicious incident — be as observant as possible without jeopardizing personal safety and report the incident to police as soon as possible," police said in Sunday's Nixle alert.

"It is heartening that our student did exactly the right thing in this suspicious and scary circumstance by running away and finding the nearest trusted adult to provide assistance," Manno said in Saturday's Facebook post.

Police "determined that our students are safe and there is no threat as a result of the matter," Manno said.

County police urged people to report any suspicious activity by calling them at 914-241-1100.
